Abstract (en)

[origin: CA1139243A] The present invention relates to improvements in centrifugal separators of the cyclone type, in which the liquid or gaseous fluid to be purified passes through an inlet blading which is sectioned so as to cause the fluid to rotate rapidly in so-called irrotational flow or regime with uniform longitudinal component, around high voltage electrode. An outlet device firstly comprises a convergent portion which partly converts the energy of rotation into energy of longitudinal translation, then a blading which completes the conversion, and finally a divergent portion in which the excess of dynamic pressure of flow is converted into static pressure in order to recover as much as possible of the energy applied to the fluid upstream of the inlet of the cyclone device. The separated particles are evacuated through a tangential outlet The invention is more particularly applicable to the purification of fluids.

Abstract (fr)

Le fluide liquide ou gazeux à épurer traverse l'aubage d'entrée (8) profilé de manière à le faire tourner rapidement suivant le régime irrotationnel avec composante longitudinale uniforme, autour de l'électrode haute tension (14). Le dispositif de sortie (5) comprend d'abord un couvergent (9) qui transforme en partie l'énergie de rotation en énergie de translation longitudinale, puis un aubage (13) qui achève la transformation, et enfin un divergent (11) dans lequel l'excès de pression dynamique d'écoulement se transforme en pression statique afin d'achever de récupérer au maximum l'énergie appliquée au fluide en amont de l'entrée (4) du dispositif cyclone. Les particules séparées sortant tangentiellement en (15). Epuration des fluides.
